A Backhaus 8" (20 cm) towel clip is primarily used in surgery to secure sterile drapes to a patient's skin. It is also used for grasping tissue and can be used for holding or reducing small bone fractures. 

Securing surgical drapes:

The clamp's pointed, inward-curving jaws are designed to firmly hold both the sterile drapes and the patient's skin to create a stable and sterile surgical field.

Grasping tissue:

It is a perforating clamp that can be used to grip and hold tissue during procedures. 

Bone fracture management:

Can be used to hold or reduce small bone fractures.
